Question

(3) A block of concrete weighs 900 N and its base is a square of side 2.0 m . What pressure does the block exerts on the ground ?

Answer 1

Answer:

450 N / m^2

Explanation:

Given,

Force ( F ) = 900 N

Area ( a ) = 2 m^2

To find : Pressure = ?

Formula : -

Pressure = F / a

               = 900 / 2

Pressure = 450 N / m^2

Answer 2

Answer:

225 Pa

Explanation:

Area of the base = 2m × 2m = 4m^2

Pressure = Force/ Area

=> 900 N / 4 m^2

=> 225 N/m^2

=> 225 Pa
